MEANS FOR FILLING A COLLECTOR WITH FIBER-WOUND BOBBINS Filed March 31, 1954 United States Patent MEANS FOR FILLING A COLLECTOR WITH FIBER-WOUND BOBBINS Walter Schweiter, Horgen, Switzerland, assignor to Maschinenfabrik Schweiter A. G., Horgen, Switzerland, a Swiss company Application March 31, 1954, Serial No. 420,129 Claims priority, application Switzerland April 8, 1953 8 Claims. (CI. 5359) The present invention relates to a collector for bobbins wound with yarn and a device for filling a collector with said bobbins. In weaving mills where various types of yarns are processed at the same time, it is advantageous to attach to each automatic winder a bobbin filling device by means of which the bobbins are automatically filled into easily transportable collectors. A known method is to use for this purpose bobbin collectors into which the bobbins ejected from the automatic winder drop, although in this process the yarn coils are damaged by the bobbins falling on top of one another. The object of the present invention is to eliminate these drawbacks in the filling of bobbin collectors. The invention consists in the fact that the lower part of the bobbin collector possesses a filling hole which closes automatically and that the automatic winder is provided with a bracket on which these collectors are mounted, a chute along which the bobbin released from the automatic winder is conveyed to the filling hole of the collector, a lever actuated from the automatic winder for the purpose of pushing the bobbin in the chute into the collector, as well as a feeler which penetrate into the collector and stops the automatic winder when the collector is full of bobbins.

A typical embodiment of the invention is illustrated in the attached drawing. In the drawing:

Fig. 1 is a side view of the bobbin collectorand of the bobbin filling device which is in operative connection with an automatic winder;

Fig. 2 is a section through the bobbin filling hole of the collector taken along the line II in Fig. 1.

On the stand 1 a row of automatic winders 2 are arranged next to one another and generally in one direction only. Secured to the stand 1 beneath each automatic winder are two frames 3 which are interconnected by means of stop bars 4 and 4a. The two frames 3 possess a bracket 5 which serves to hold in position a transportable bobbin collector 6. The transportable bobbin collector 6 has a bottom or base 6a with a bobbin filling hole 6b and possesses only three side walls so that the collector is open at 60. Arranged between the two frames 3 is a bobbin chute 7, designated by dotted lines, through which the finish-wound bobbins 8 reach the filling station 9. The latter possesses a longitudinal slot 9a through which the lever 10 penetrates for the purpose of pushing bobbin into the collector. The said lever 10 is rotatably located on the pin or shaft 12 which serves as connecting rod between the two frames 3. The channel 7, designated by dotted lines, is only used if the bobbins pass head first into the collector 6, a procedure which, however, is undesirable in the majority of cases because then the heaviest part of the bobbins comes to rest on the open side 60 of the collector 6. In order to lay the bobbins in the box 6 so that they are clearly arranged and their pointed ends are directed toward the front, a pivotally mounted chute portion 7a is provided for as seen in the attached drawing. This chute portion is rotatably secured on a pivot rod 14 and is provided with a counterweight 15. The foremost tongue 70 of the chute 7a thrusts against the funnel 16 "ice which is in operative connection with the automatic winder 2. When the bobbin 8 falls out of the funnel 16 into the chute 7a, it thrusts against the stop 17 of the chute 7a. Since, now, the bobbin 8 in the chute 7a is heavier than the counterweight 15, the chute 7a pivots relative to the remainder of the chute into the position designated by 7b so that the bobbin turns end over end and then slides to the filling portion or station 9. Special mechanisms are provided between the automatic winder and collector. The cam shaft 20 of the automatic winder 2 makes one revolution at each change of bobbin. Mounted on this cam shaft is a crank 22, the pin 23 of which engages with the fork 24 of lever 25. Arranged at the end 25a of lever 25 is a stop plate 26 which at the beginning of the bobbin change is in the position marked in dotted lines for temporarily retaining a released bobbin. During the revolution of the shaft 20 the releasingplate 26 shifts to full line position and discharges the bobbin 8.

Also secured to the shaft 20 is a curved disc 28 along which runs the roller 29 secured to the one-armed lever 30. The lever 30 is pivotally mounted to swing about a I bolt 32, its front end being connected to the guide rod 33, the bottom end of which is secured to the rear arm 10a of the two-armed lever 10.

On completion of the winding process, when the desired length of coil has been obtained, the winding apparatus is inactivated and the bobbin changing apparatus is activated. The single revolution of the shaft 20 is eifected by means of a cam (not shown), revolution of the shaft 20 producing the inactivation of the winding apparatus and the activation of the bobbin changing apparatus by mechanism which is well-known and which does not constitute a part of the present invention.

7 The counter member 41 normally serves to press the bobbin 8 against the carrier 42 of the winding mechanism, but upon revolution of the shaft 20 the thread carrier 40 together with the member 41 return to their initial position in which they are displaced to the left of the position shown. The movement of the member 41 frees the bobbin 8 and the latter falls below. The means for supplying a new bobbin to the winding apparatus is also known per se and an example of suitable means is described in U. S. Patent No. 2,639,098.

Revolution of the cam shaft 20 also serves to move the lines.

process is completed. Meanwhile, the lever end or pusher element 10, which is moved by the camshaft 29 via the curved disc 28, roller 29 and levers 30 and 33, assumes its upward position and pushes a bobbin, which at the end of the previous bobbin change has reached the station of portion 9, through charging hole 9a in the base wall of the collector 6 thereinto and then returns to its lower or rest position. At the end of the bobbin change the funnel or chute 16 is again opened at the first portion of the chute by stop or release plate 26, which is swung outwardly, whereupon another bobbin slides down the chute to a portion thereof at 7a, is then tilted together with hinged chute portion 7a about an arbor 14 and finally reaches the second portion at 9, where it remains until the next bobbin change takes place.

When the bobbin collector is practically filled with bobbins, the automatic winder must be stopped. For this purpose a feeler lever 35 is secured to the funnel 16 and penetrates into the collector 6 through an opening or slot 36 in the collector top wall. As soon as the collector is full, the topmost bobbin presses the feeler 35a of the lever into dotted line position and by means of the rod 37, which is in operative connection with the stop motion mechanism 38 of the automatic winder, shuts down the latter.
